Benefits of battery storage

Batteries allow you to store your excess solar energy and use it when you need instead of sending it to the grid. At night time, when your solar PV system is not producing power, you can use battery power to run your home, and in the event of a power outage, some batteries can provide you with back-up power.

Optimising Solar Power

Excess solar energy produced during the day is sold back to the retailer for a fraction of what home owners pay. Now energy storage systems will enable home owners to store their excess energy and use it at peak times, like late afternoon. This increases self consumption of solar energy and improves the return from a solar power system.

Peak Shaving

Almost all energy providers offer time of use tariffs. These tariffs charge a premium for energy during peak times, like the middle of the day in summer, while offering lower rates during non peak times. Energy storage systems enable homes to purchase and store energy at non peak times and use it at peak times, reducing their energy costs.

Backup Power

Energy storage systems can be configured to provide backup power in the event of an outage. Home owners can choose to run their whole house, or configure essential circuits – like lights, fridges, security, fire alarms, internet or medical equipment. This is perfect for people in remote or unreliable power areas or for those who can’t risk losing power.

Types of Energy Storage Systems

Storage systems for the home can fall into three main categories, DC Coupled, AC Coupled and Hybrid. Retrofitting is possible, however those purchasing new systems are encouraged to purchase a Hybrid inverter, for direct battery connection now or later. Each option has benefits and drawbacks, so consultant with an expert to determine which is right for you.
